I'm playing with supporting custom stack map formats with statepoints. While doing so, I noticed that the existing implementation didn't indicate inherently unsized frames. This change essentially just ports the functionality that already exists for the default StackMaps section to custom stackmaps. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@233891 91177308-0d34-0410-b5e6-96231b3b80d8
